Daniel 1:6-8

Now among these were, of the children of Judah, Daniel, Hananiah, Mishael, and Azariah. And the prince of the eunuchs gave names unto them: unto Daniel he gave the name of Belteshazzar; and to Hananiah, of Shadrach; and to Mishael, of Meshach; and to Azariah, of Abed-nego. But Daniel purposed in his heart that he would not defile himself with the king’s dainties, nor with the wine which he drank: therefore he requested of the prince of the eunuchs that he might not defile himself.
